THIS APPLICATION IS A U.S. NATIONAL PHASE APPLICATION OF PCTINTERNATIONAL APPLICATION PCT/JP2004/015472.

TECHNICAL FIELD

The present invention relates to the ventilation structure of built-inheating cookers.

BACKGROUND ART

In the ventilation structure of a conventional built-in heating cooker(cooker), an air inlet is typically provided at the front bottom of thecooker and an air outlet is provided at the side rear of the cooker. Inaddition, a cooker-supporting face is located further in toward thecooker than the air outlet.

The Japanese Patent Laid-open Application No. H11-354263 discloses oneof this type of cookers.

FIG. 11 shows the ventilation structure of a conventional cooker. Asshown in FIG. 11, top plate 2 configured typically with a ceramic plateis placed and bonded on support 1 constituting the top part of thecooker body. Opening 3 (air outlet) for allowing air from inside thecooker to escape is provided at the side rear of support 1.Cooker-supporting face 4 of support 1 for supporting the cooker itselfis formed further inward of the cooker from opening 3. Frame 5 isconfigured further inner than cooker-supporting face 4, and disposed oncabinet 6. Wall 8 to prevent ingress of spilled liquids is providedinside opening 3 (air outlet) on flange 7 of frame 5. Cooling air forcooling the cooker's internal space passes through between support 1 andflange 7, and support 1 and wall 8, then exits from opening 3. However,in this conventional structure, the small distance between opening 3(air outlet) and the cooker's internal space is likely to allow spilledliquids from outside enter inside the cooker body. Accordingly,provision of wall 8 is necessary for blocking spilled liquids.

On the other hand, wall 8 cannot be simply provided. A complicatedlayout, such as alternately disposed multiple walls, is needed forsecuring cooling performance. As a result, the top part cannot be madethin. In other words, it is difficult to provide both reliableprotection against spilled liquids (countermeasures against spilledliquids) and good cooling performance.

Still more, since an edge of top plate 2 is exposed, the edge needs tobe treated (e.g., by chamfering) to protect the user from injury whileusing the cooker.

More specifically, since the edge is exposed as a component, an extrawork of edge treatment needs to be provided, and the area of top plate 2itself cannot be made broader.

Still more, the space between top plate 2 and flange 7 is the narrowestof the necessary spaces (under top plate 2) for maintaining coolingperformance, and is also the space which needs to be secured withoutfail.

However, since the support for the top plate is not directly provided,top plate 2 warps and results in insufficient cooling space in somecases.

Still more, since there is no sealing material between the bottom partof the cooker and cabinet 6, liquids that spill on the top plate passesthrough under cooker-supporting face 4, penetrates under the cookerwhich is inside cabinet 6, and may result in flooding inside cabinet 6.

The present invention solves the above disadvantages of the prior art,and provides a highly reliable cooker which satisfies both good coolingperformance and features effective countermeasures against spilledliquids.

Furthermore, this cooker has a broad space on the top plate for easycooking and easy cleaning.

SUMMARY OF THE INVENTION

A built-in cooker of the present invention includes a top plate, asupport for supporting the top plate from below, a top frame coveringthe edge of the top plate and a frame constituting the cooker body. Thesupport has a cooker-supporting face for supporting the cooker, and thisis provided outside of a top plate-supporting face. A first opening isprovided on at least one side wall provided between the topplate-supporting face and the cooker-supporting face. A second openingis provided on the frame in a position corresponding to the firstopening at a predetermined distance.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Exemplary embodiments of the present invention are described below withreference to drawings. The drawings are schematic views and thus do notaccurately indicate dimensional positions. For reasons of simplicity,components with the same structure are given the same referencenumerals. Curved arrows in the solid line in the drawings indicate themovement of spilled liquids or boiled-over soup.

The exemplary embodiments described hereafter do not limit the scope ofthe present invention.

First Exemplary Embodiment

A first exemplary embodiment is described below with reference to FIGS.1 to 4.

As shown in FIGS. 1 to 4, top plate 11 where pots are placed issupported from underneath by top plate-supporting face 13 of support 12.Top plate 11 is typically made of a ceramic plate. Top plate 11 and topplate-supporting face 13 are fixed and bonded with heat-resistantadhesive 14. Top frame 15 is provided around the edge of top plate 11 soas to cover its periphery, and top plate 11 and top frame 15 are fixedwith adhesive 14. Frame 16, constituting the cooker body, is providedinside support 12. Cooker-supporting face 17 is formed outside of topplate-supporting face 13, and the cooker is supported by placing thiscooker-supporting face 17 on cabinet 18.

Side wall 19 is integrally formed between top plate-supporting face 13and cooker-supporting face 17. Multiple first openings 20 are providedon the surface of side wall 19, configuring a path for letting air inand out to and from the cooker's internal space. In addition, secondopenings 21 are provided on top frame 15 in positions corresponding tofirst openings 20 with a predetermined distance (ex. 15 mm) in between,also configuring a path for letting air in and out.

The operation and function of the ventilation structure of the built-inheating cooker as configured above are described next.

In the above configuration, the case of spilling water over top plate 11is examined. Most of the spilled water is blocked by top frame 15, butsome water enters via second openings 21. Since there is a space ofabout 15 mm between first openings 20 and second openings 21, the waterremains in the space between top frame 15 and support 12.

Naturally, some water penetrates further inside the cooker. However,side wall 19 blocks it, and almost no water enters into the cooker'sinternal space where live part 10 is located. The live part in thisexemplary embodiment refers to a part not or not sufficientlyelectrically insulated. An example of the live part is a substrate uniton which electrical components are placed and electrically coupled on aprinted wiring board. The live part is also present in drawings otherthan FIG. 3 but it is omitted for simplification.

As described above, ingress of water from outside is preventable by thissimple structure that provides a predetermined space between firstopenings 20 and second openings 21.

In addition, support 12 contacts top plate 11 by top plate-supportingface 13, and also contacts cabinet 18 by cooker-supporting face 17 viaside wall 19.

Since top plate 11 and pots are supported so as to fully secure alimited space between top plate 11 and cabinet 18, and the open area offirst openings 20; the ventilation path is always open, achieving fullysatisfactory cooling performance.

Water overflow into cabinet 18 is also preventable becausecooker-supporting face 17 supports the cooker body and contacts cabinet18.

Furthermore, top frame 15 constituting second openings 21 is not only afirst impediment to water entering the cooker's internal space but alsoa protection covering top plate 11. Since the edge of the top plate 11is hidden, no additional processing of full-edge treatment forpreventing injuries by top plate 11 is needed, and an easy-to-clean toppart is achieved. Still more, since second openings 21 are provided on arear side face, the top surface is smooth without any holes. This offersan easy-to-clean cooker with a sleek design.

As described above, in the first exemplary embodiment, thecooker-supporting face is formed outside first openings 20 on the sidewall of the support. In addition, the second openings are provided onthe top frame in a position corresponding to the first openings, with apredetermined distance in between. This enables, by means of a simplestructure, the prevention of liquids entering the cooker's internalspace. In other words, this exemplary embodiment offers a highlyreliable cooker both designed to cope with spilled liquids and with goodcooling performance. The smooth top plate also achieves good design andeasy cleaning.

Accordingly, the first exemplary embodiment achieves a thin top part(about 10 mm max.) and offers a structure that can secure the air ventfor cooling inside the cooker on its top part.

This exemplary embodiment has an air inlet and outlet. However, the sameeffect is achievable with the structure only of the air inlet or outlet.

This exemplary embodiment also refers to one side at the back. However,the first openings and second openings can be provided on the back, andleft and right sides. Still more, the same effect is achievable byproviding the openings in different positions, such as only on the rightside, depending on conditions, such as how the cooker is installed orthe cooling system of the cooker. Furthermore, the same effect isachievable by making the bottom of the side wall against the top platetilted obtusely outward (e.g., about 90 to 135°).

Second Exemplary Embodiment

A second exemplary embodiment is described below with reference to FIG.5.

As shown in FIG. 5, the basic structure is the same as in the firstexemplary embodiment, and thus only the structure different from thefirst exemplary embodiment is described.

Flange 22 is provided on the periphery of frame 16. Flange 22 isdisposed over cabinet 18.

Side wall 19 of support 12 is located further inward towards thecooker's internal space than end 23 of flange 22. Flange 22 andframe-supporting face 24, provided between side wall 19 andcooker-supporting face 17, are in contact.

The operation and function of the ventilation structure of a built-inheating cooker as configured above is described next.

Also with respect to operation and function, only the parts differentfrom the first exemplary embodiment are described.

The case of spilling water over top plate 11, and water further enteringinside from first openings 20 is examined next. Water (indicated by ‘X’in FIG. 5) entering from first openings 20 flows over flange 22. Sinceside wall 19 is placed on flange 22, and frame-supporting face 24 andflange 22 are in surface contact; water does not leak fromframe-supporting face 24 and flange 22 to underneath flange 22. Inaddition, side wall 19 presses flange 22 downward, increasing thetightness of the seal.

As described above, the second exemplary embodiment provides a flange onthe periphery of the frame, and the side wall of the support is disposedinner toward the cooker than the flange end. The flange and the outerframe-supporting face provided between the side wall andcooker-supporting face are in contact. This structure prevents leakageof water from the cooker to inside the cabinet, even if water entersfrom the first openings. A highly reliable cooker with significantlyimproved sealing capability can thus be offered. The sealing capabilitycan be further improved by applying a sealing material betweenframe-supporting face 24 and flange 22.

It is apparent that the same effect as that described in the firstexemplary embodiment is also achieved in the second exemplaryembodiment.

Third Exemplary Embodiment

A third exemplary embodiment is described next with reference to FIG. 6.

As shown in FIG. 6, the basic structure is the same as the secondexemplary embodiment, and thus only the structure different from thesecond exemplary embodiment is described.

Side wall 19 is provided underneath top plate 11.

The operation and effect of the ventilation structure of the cooker asconfigured above is described next.

Also for the operation and function, only the parts different from thesecond exemplary embodiment are described.

Side wall 19 having first openings 20 is located underneath top plate11. This enables the securing of space between top plate 11 and flange22. In other words, the ventilation path can be fully secured.Accordingly, both good cooling performance and countermeasures againstspilled liquids are achieved.

In addition, side wall 19 is disposed under top plate 11. This meansthat cooker-supporting face 17 can be positioned further inward towardsthe cooker's internal space. This allows shortening of the width of topframe 15 covering top plate 11 and supporting plate 12. Consequently,the area of top plate 11, which is the cooking area, can be madebroader. Still more, since second openings 21, which are originally airvents, are not provided on the top face, the cooking area can be yetfurther broadened. Still more, a smooth surface without any holes makescleaning extremely easy and gives a neat appearance. There is a slightgap between top frame 15 and top plate 11, and the top frame is higher.This gap acts as a stopper for the pot in use if the pot deviates andmoves to the end of the top part, preventing the pot from falling. Thus,safety is also improved.

As described above, the third exemplary embodiment has the side wallunderneath the top plate. This assures good cooling performance by fullysecuring the ventilation path between the top plate and support, as wellas countermeasures against spilled liquids, offering a highly reliablecooker. Furthermore, this exemplary embodiment offers an easy-to-cook,easy-to-clean, high-safety and easy-to-use cooker with a broad topplate.

It is apparent that the same effect as that described in the firstexemplary embodiment is also achieved in the third exemplary embodiment.

Fourth Exemplary Embodiment

A fourth exemplary embodiment is described next with reference to FIG.7.

As shown in FIG. 7, the basic structure is the same as in the thirdexemplary embodiment, and thus only the structure different from thethird exemplary embodiment is described.

Wall 25 is integrally provided with support 12 on the periphery ofcooker-supporting face 17 of support 12.

The operation and function of the ventilation structure of the built-inheating cooker as configured above is described next.

Also with respect to operation and function, only the parts differentfrom the third exemplary embodiment are described.

The case of spilling water over top plate 11 is examined. Secondopenings 21 are provided on top frame 15. Second openings 21 can beextended even to the face contacting cabinet 18. However, wall 25 isprovided on the entire periphery of cooker-supporting face 17 of support12.

Consequently, wall 25 blocks ingress of water on cabinet 18 and inthrough second openings 21, and amount of water entering inside topframe 15 can be significantly reduced.

In addition, since wall 25 is processed by bending the rim of support12, the strength of support 12 can be sufficiently secured.

Accordingly, the third exemplary embodiment blocks water from enteringinside the cooker body from the first. Countermeasures against spilledliquids and good cooling performance are thus both achievable.

As described above, this exemplary embodiment provides the wall on theperiphery of the cooker-supporting face. This offers a highly reliablecooker with further protection for ingress of spilled liquids. It isalso apparent that the same effect as that described in the firstexemplary embodiment is also achieved.

In the above description, the wall is integrally made with the support.The same effect is also achievable by the use of a separate componentfor the wall.

Fifth Exemplary Embodiment

A fifth exemplary embodiment is described with reference to FIG. 8.

As shown in FIG. 8, the basic structure is the same as in the fourthexemplary embodiment, and thus only the structure different from thefourth exemplary embodiment is described.

Sealing material 26 is provided underneath cooker-supporting face 17 ofsupport 12.

The operation and function of the ventilation structure of a built-inheating cooker as configured above is described next.

Also with respect to operation and function, only the parts differentfrom the fourth exemplary embodiment are described.

The case of spilling water over top plate 11 is examined.

Water flows toward the cooker body. However, since sealing material 26is provided on the entire circumference underneath cooker-supportingface 17, water does not enter from between the cooker body and cabinet18. This significantly improves countermeasures against ingress ofspilled liquids to inside cabinet 18.

Sealing material 26 can be provided typically by applying silicone foamor a sealing tape. Any other means with sealing effect are applicable.

As described above, the fifth exemplary embodiment applies the sealingmaterial on the entire circumference underneath the cooker-supportingface. This offers a highly-reliable and easy-to-use cooker preventingingress of water to inside the cabinet.

Sixth Exemplary Embodiment

A sixth exemplary embodiment of the present invention is described withreference to FIGS. 9A, 9B and 10.

As shown in FIGS. 9A, 9B and 10, the basic structure is the same as thefifth exemplary embodiment, and thus only the structure that isdifferent is described below.

Cover 27 is attached to the side face of top frame 15 in a way such asto cover second openings 21. Cover 27 includes top face 28, cover sidewall 29 and bottom face 30. Cover side wall 29 has multiple thirdopenings 31, and elastic member 32 with spring force is provided at bothits ends. Cover 27 is detachably mounted on top frame 15 by fitting thiselastic member 32 to both ends of the second openings. Both secondopenings 21 and third openings 31 are provided on the side face overfirst side face 33 and second side face 34 disposed from the bottom endof top frame 15 and cover 27 respectively.

With respect to cooling structure, the air cooling the cooker's internalspace passes between frame 16 and top frame 15, first openings 20,second openings 21, cover 27 and third openings 31, then exits thecooker.

The operation and function of the ventilation structure of the cooker asconfigured above are described next.

Also for the operation and function, only the parts different from thefifth exemplary embodiment are described.

First, the case of boiled-over soup that pools at the back of top plate11 in the above structure is examined. Boiled-over soup drips down covertop face 28 to cabinet 18. However, it does not enter inside cover 27because cover 27 is attached to the back of top frame 15 and there is noopening on top face 28.

Even if a large volume of boiled-over soup drips onto cover 27, the flowof boiled-over soup on cabinet 18 mostly blocked by cover side wall 29and second side wall 34 on the same face. Consequently, only a littleenters inside cover 27. However, since third openings 31 for coolinginside the cooker are provided, a certain amount of boiled-over soupenters them. The boiled-over soup passing through third openings 31 ispooled in a space inside cover 27, and thus it does not yet enter insidethe cooker.

The boiled-over soup still reaching further inside is blocked by theside face of top frame 15 and wall face A33, and thus hardly any entersinside the cooker. It is preferable that second openings 21 and thirdopenings 31 are disposed alternately, as seen from the back. In thisway, a structure that further prevents entrance of boiled-over soup isestablished, although ventilation becomes slightly less efficient.

Since cover 27 is detachable, it can be easily removed and cleaned. Inother words, even when third openings 31, which are the air vents, arestained and clogged with boiled-over soup, etc., detachable cover 27 canbe easily removed and cleaned to keep cover 27 clean and thus maintainthe original performance.

A detachable system is made feasible by providing elastic member 32 withspring force at both sides of cover 27. Cover 27 is attachable to anddetachable from top frame 15 just by pushing and pulling, although it isat the back where attachment is difficult.

In addition, the spring structure allows firm attachment without a gap,although the side face lacks stability.

As described above, the sixth exemplary embodiment offers a structurethat makes it difficult for boiled-over soup to enter the cooker andalso secures good cooling performance. In addition, the cover is easilydetachable for cleaning. Accordingly, this exemplary embodiment offers ahighly reliable cooker with easy cleaning and easy attachment.

Elastic member 32 can be integrally made with cover 27, or separatelymade and fixed to cover 27 by spot welding, screwing, etc. Commonelastic members are usable as material for elastic member 32.

With respect to the detachable system, any detachable means isapplicable.

For example, a leaf spring is provided inside the top, and the face withcover can be sandwiched and fixed between the leaf spring and the topface. Or, if the top and cover are made of magnetic material, a magnetcan be provided on both or either part. Alternatively, a tab with aspring structure can be hooked to the top, and detached by a singletouch.

Alternatively, a protrusion can be made on a resin member fixed to thecover, and this is press-fitted to the second openings as a detachablemechanism.

Next, the characteristics of the present invention are summarized asbelow.

The cooker of the present invention includes the top plate; the supportsupporting the top plate from underneath; the top frame covering theedge of the top plate; and the frame constituting the cooker body. Thesupport has a cooker-supporting face for supporting the cooker outsideof the top plate-supporting face. The first openings are provided on atleast one side wall between the top plate-supporting face andcooker-supporting face. The second openings are provided on the topframe at positions corresponding to the first openings at apredetermined distance. This structure readily secures the space in thetop frame, reduces ingress of water to the cooker's internal space, andsecures the cooling path. The present invention thus offers a highlyreliable cooker with good cooling performance.

Still more, the cooker of the present invention provides a flange on theperiphery of the frame, and the side wall of the support is positionedfurther inward of the cooker body than the flange end. In addition, theflange and the frame-supporting face provided between the side wall andthe cooker-supporting face are in contact. This offers a highly reliablecooker with further improved sealing against leakage of water betweenthe cooker and cabinet to the inside of the cooker.

Still more, the cooker of the present invention has a side wallunderneath the top plate. This enables the side wall to directly supportthe top plate, and thus the ventilation path between the top plate andsupport is fully secured. More specifically, a highly reliable cookerwith both countermeasures against spilled liquids and good coolingperformance are made feasible. Still more, disposition of thecooker-supporting face inward of the cooker body reduces the width ofthe top frame covering the top plate and supporting plate. Consequently,a broader top plate area offers a user-friendly cooker that has superiorworking space for cooking and affords easy cleaning.

Moreover, the cooker of the present invention has a wall on theperiphery of the cooker-supporting face. This reduces the risk of waterdripping on the cabinet through the second openings to inside thecooker, offering high reliability.

Furthermore, the cooker of the present invention is provided withsealing material on the entire circumference of the bottom of thecooker-supporting face. This prevents entrance of water passingunderneath the cooker-supporting face to underneath the cooker bottom,which is inside the cabinet. Accordingly, a highly reliable andeasy-to-use cooker is made feasible.

The built-in heating cooker of the present invention has an air vent onthe top part, and has a cooker-supporting face outside the firstopenings provided on the side wall of the support and the secondopenings on the top frame in positions corresponding to the firstopenings at a predetermined distance. This allows the entry of waterinside the cooker to be prevented by means of a simple structure. Inaddition, provision of a top frame broadens the space on the top plate,offering a safe and easy-to-clean cooker that has superior working spacefor cooking with much reduced risk of pots sliding off. Moreover, theprovision of openings at the rear side face slims the top part (by about10 mm) that appears on the cabinet, and also achieves a smooth and flattop plate without any holes. Accordingly, the present invention alsooffers a cooker with a sleek design in addition to good coolingperformance and features effective countermeasures against spilledliquids.
